PhotoCraft is a clean‑room reimplementation of Photoshop written entirely in Rust, aimed at delivering a native, high‑performance image editor that reads and writes real PSD files. It targets macOS, Windows, Linux, FreeBSD and the web, is open source under MIT/Apache‑2.0, and is in early alpha. The engine uses a GPU compositor built on wgpu (Metal, Vulkan, DX12, WebGPU), copy‑on‑write tiled images and multithreaded filters; examples cite a radius‑180 Gaussian blur on a 3.6 MP image running in under a second. PSD compatibility is strong - re‑saving preserves the render of 307 of 309 psd‑tools test files and 116 of 116 shape layers match Photoshop pixels.
Functionally it reproduces Photoshop workflows: layers, masks, adjustment layers (16 built‑in, including Curves and Levels with live histograms), layer styles (shadows, glows, bevels, overlays), editable type, vector shapes, full selection toolset (including Select Subject/Object Selection), smart objects and a real brush engine with dynamics and deterministic strokes. Every UI action is a command so the same engine can be driven from UI, CLI, JSON control channel or an MCP server, enabling automation and agent control. The project includes tool lists, filters (many preview live), history and non‑destructive transforms, export options with size estimates, and community channels for contribution.
